Support for Swift on Linux & Windows?

[ghost]

Is your feature request related to a problem? Please describe.

xmake mentions that Swift is one of supported languages, however. After attempted use of it on Windows or Linux I found that it will not work on those two OS's as I receive errors trying to use it. Swift is a cross-platform language now (or at least is getting there.) for Linux and Windows (still heavily WIP, and a lot of issues facing with SPM can be solved with CMake).

I would love to see xmake add ability to use it and Swift outside of Apple ecosystem, as you can easily use the language outside it.

Describe the solution you'd like

As mentioned above. Add Linux & Windows support for Swift to xmake.

Describe alternatives you've considered

CMake is the only alternative solution for current issues with Swift on Windows, but I would sincerely prefer to use xmake over it.

I supported it on linux, windows. But I only test it on linux.

$ xmake f -c -vD
$ xmake -rvD
[ 25%]: compiling.release src/main.swift
/mnt/swift-5.5.2-RELEASE-ubuntu20.04/usr/bin/swiftc -c -O -o build/.objs/test/linux/x86_64/release/src/main.swift.o src/main.swift
[ 50%]: linking.release test
/mnt/swift-5.5.2-RELEASE-ubuntu20.04/usr/bin/swiftc -o build/linux/x86_64/release/test build/.objs/test/linux/x86_64/release/src/main.swift.o -Xlinker -s
[100%]: build ok!

Awesome! can't wait to try it out!
